Been screwing around in the Ghost Recon beta these last few days. Gotta say the game is fun but you can definitely tell it was made to be played with friends. Don't get me wrong the A.I. squad mates are better then what you would get in other games (almost as good as the A.I. squad mates from Rainbow Six Vegas 2 (which this game has some similar mechanics to)) but a lot of the missions seem to be built with the idea of going in with 3 other players due to enemy patrol routes and placements. Beyond that gun play is pretty solid (a little wonky at times but this is a beta), combat is quick and sometimes relentless (I made a minor mistake approaching a base in the new area for the beta and damn near paid for it with my life (fucking enemies called in 2 choppers, still trying to figure out how I survived it)), and the story is pretty good for a Tom Clancy game (not generally into Tom Clancy stuff but this game and the Rainbow Six games have always had relatively good stories to go along with good game play).
Honestly if it wasn't coming out a week after Horizon and two weeks before Andromeda I'd probably buy it but no, Ubisoft had to pick the worst time to release it. If you get a chance this weekend try it out, the beta runs until Monday and it's definitely worth a quick play through (even if you don't get through the entire first area you'll get a good feel for the game play and what the story is about in the first few missions).
